How your royalties are calculated.

Four factors that decide what lands in your bank account.

Step 01

Print on Demand

Single-copy printing. Zero upfront inventory. Your book is stored digitally and printed only when ordered — so you never pay to stock unsold copies.

Step 02

Smart Pricing Floor

We calculate the lowest MRP that keeps your royalty positive after production, marketplace fees, and GST. Set your price above this floor — you choose.

Step 03

Marketplace Channel

Amazon, Flipkart, and other retailers take a standard distribution cut. We pass on the rest to you — no hidden Penray share.

Wider reach, lower per-copy

Step 04

Penray Direct Royalty

Sales on Penray's own storefront skip the marketplace cut. Only a flat handling cost. Higher royalty per copy — every time.

Questions

Six answers about royalty & pricing.

Stuff most authors ask before they start.

When do royalties actually hit my account? +

On the 10th of every month for sales settled in the previous month, paid via UPI or NEFT. The first payout is in the month following your launch month.

Where can I see live sales numbers? +

You get a private dashboard at /author/dashboard showing units sold per channel, revenue, and projected royalty for the month. Updated daily from each platform's API.

What if a sale gets refunded after I have been paid? +

Refunds settle automatically against the next month's royalty. You will see the reversal as a line item on the dashboard. We never claw back money that has already been paid out — only future months net the adjustment.

Is there a minimum payout threshold? +

Yes. Royalty payments are initiated once your royalty balance reaches ₹1,000. Upon reaching the threshold, ₹500 is transferred to your registered bank account, while the remaining balance is maintained as a reserve for any future adjustments, including book returns, promotional discounts, damaged copies, or marketplace reconciliation. Any remaining balance continues to accumulate and is included in future royalty payouts.
